Description

Snapshot processing method and device and terminal

Technical Field

The present application relates to the field of terminals, and in particular, to a method, an apparatus, and a terminal for processing a snapshot.

Background

With the continuous evolution of systems (e.g., android, hong meng) of intelligent terminals (e.g., mobile phones), the number of applications in the intelligent terminals is increasing, and the memory occupied by each application is also increasing. The situation that the available storage space of the terminal cannot meet the normal operation of the system often occurs.

In the current intelligent terminal system, when an application exits to a background, the intelligent terminal generates a screenshot of a current application interface, and the screenshot of the current application interface is called as an application snapshot. And the intelligent terminal stores the snapshot of the application into the available storage space of the terminal. When the application appears in the foreground again, the intelligent terminal loads the application by using the snapshot of the application stored in the available storage space, and the application is directly restored to the page corresponding to the snapshot. However, 6M to 10M of the available memory space is occupied by one snapshot. When the number of applications running in the background in the terminal is increased, the corresponding snapshots occupy more and more memory, so that the available storage space of the intelligent terminal is further reduced. If the available storage space value of the intelligent terminal is lower than the memory value meeting the system operation, the smoothness of the intelligent terminal system operation can be influenced.

The application provides a snapshot processing method, a snapshot processing device and a terminal, which are used for flexibly processing a snapshot according to memory information of the terminal.

In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, the present application provides a method for processing a snapshot, the method comprising: the terminal determines the available storage space of the memory of the terminal; the terminal determines the compression ratio of the snapshot in the processing terminal according to the relation between the available storage space and a preset threshold, wherein the compression ratio is a first compression ratio or a second compression ratio; the terminal processes the snapshot according to the compression ratio; the storage space occupied by the snapshot processed by the first compression ratio is larger than that occupied by the snapshot processed by the second compression ratio.

Based on the above technical solution, the method for processing a snapshot provided by the present application: and the terminal determines the proportion of processing the snapshot according to the available storage space of the memory of the terminal. The terminal processes the snapshot according to the determined compression ratio; the storage space occupied by the snapshot processed by the first compression ratio is larger than that occupied by the snapshot processed by the second compression ratio. Therefore, the terminal can flexibly process the snapshot by adopting different compression ratios according to the size of the available storage space of the terminal memory.

In a possible implementation manner, the determining, by the terminal, a compression ratio of a snapshot in the processing terminal according to a relationship between an available storage space and a preset threshold includes: when a first preset condition is met, the terminal determines that the compression ratio is a first compression ratio; wherein the first preset condition is as follows: the available storage space is greater than or equal to a first preset threshold; alternatively, the available storage space is greater than or equal to a first preset threshold value and lasts for a first preset time period. In this way, when the available storage space is greater than or equal to the first preset threshold, or the available storage space is greater than or equal to the first preset threshold and lasts for the first preset time period, the terminal selects the first compression ratio compression snapshot with the high compression ratio.

In a possible implementation manner, the memory state of the available storage space is a first state, and the difference between the time of marking the first state and the current time is greater than a first preset time difference, the terminal determines that the available storage space is greater than or equal to a first preset threshold and lasts for a first preset time period, and the first state indicates that the available storage space is greater than or equal to the first preset threshold. In this way, the terminal is able to determine, from the duration of the first state, a duration for which the available storage space is greater than or equal to a first preset threshold.

In a possible implementation manner, the snapshots include a first snapshot, and the first snapshot is a snapshot between a current time and a first time node; the terminal processes the snapshot according to the compression ratio, and the method comprises the following steps: the terminal processes the first snapshot according to the first compression ratio; and the terminal stores the first snapshot processed by adopting the first compression ratio in a memory of the terminal.

In this way, the terminal may select the second compression ratio with a low compression ratio to compress the snapshot when the available storage space is smaller than the second preset threshold, or the available storage space is smaller than the second preset threshold and lasts for the second preset time period, so as to reduce the storage space occupied by the snapshot.

In a possible implementation manner, the memory state of the available storage space is a second state, the difference between the time of marking the second state and the current time is greater than a second preset time difference, the terminal determines that the available storage space is smaller than a second preset threshold and lasts for a second preset time period, and the second state indicates that the available storage space is smaller than the second preset threshold. In this way, the terminal can determine the duration of the available storage space being less than the second preset threshold value according to the duration of the human state.

In one possible implementation, the snapshot includes at least one of a cache snapshot and a first snapshot, and the method further includes: the terminal stores at least one of the cache snapshot and the first snapshot in a flash memory; the terminal processes the snapshot according to the determined compression ratio, and the method comprises the following steps: and the terminal processes at least one of the cache snapshot and the first snapshot according to the second compression ratio and stores at least one of the cache snapshot and the first snapshot processed by the second compression ratio in the memory. Therefore, the terminal processes the snapshot by adopting the second compression ratio, and the storage space occupied by the snapshot can be reduced.

In a possible implementation manner, before the terminal determines, according to a relationship between the available storage space and a preset threshold, a compression ratio of a snapshot in the terminal, the method further includes: and the terminal determines the memory state of the memory according to the relation between the available storage space and the preset threshold. Therefore, the terminal can determine the relation between the available storage space and the preset threshold value by setting the memory state of the terminal.

In some embodiments, processor 101 may include one or more processing units. For example, the processor 101 may be an kylin 960 chip manufactured by Huanti technologies, Inc. In some embodiments of the present application, the processor 101 may further include a fingerprint verification chip for verifying the acquired fingerprint.

The rf circuit 102 may be used for receiving and transmitting wireless signals during the transmission and reception of information or calls. In particular, the rf circuit 102 may receive downlink data of the base station and then process the received downlink data to the processor 101; in addition, data relating to uplink is transmitted to the base station. Typically, the radio frequency circuitry includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, and the like. In addition, the radio frequency circuitry 102 may also communicate with other devices via wireless communication. The wireless communication may use any communication standard or protocol including, but not limited to, global system for mobile communications, general packet radio service, code division multiple access, wideband code division multiple access, long term evolution, email, short message service, and the like.

The memory 103 is used for storing application programs and data, and the processor 101 executes various functions and data processing of the mobile phone 100 by running the application programs and data stored in the memory 103. The memory 103 mainly includes a program storage area and a data storage area, wherein the program storage area can store an operating system and application programs (such as a sound playing function and an image playing function) required by at least one function; the storage data area may store data (e.g., audio data, a phonebook, etc.) created from use of the handset 100. Further, the memory 103 may include high speed random access memory, and may also include non-volatile memory, such as a magnetic disk storage device, a flash memory device, or other volatile solid state storage device.

Wherein the touch pad 104-1 can capture touch events on or near the touch pad 104-1 by a user of the cell phone 100 (e.g., user operation on or near the touch pad 104-1 using any suitable object such as a finger, a stylus, etc.), and transmit the captured touch information to other devices, such as the processor 101. Among them, a touch event of a user near the touch pad 104-1 can be called a hover touch; hover touch may refer to a user not having to directly contact the touchpad in order to select, move, or drag a target (e.g., an icon, etc.), but rather only having to be located near the electronic device in order to perform a desired function. In the context of a hover touch application, the terms "touch," "contact," and the like do not imply a direct contact to the touch screen, but rather a nearby or near contact. The touch pad 104-1 capable of performing floating touch can be implemented by using capacitive type, infrared sensing, ultrasonic wave, and the like. In addition, the touch pad 104-1 can be implemented by various types, such as resistive, capacitive, infrared, and surface acoustic wave. The display (which may also be referred to as a display screen) 104-2 may be used to display information entered by or provided to the user as well as various menus of the handset 100. The display 104-2 may be configured in the form of a liquid crystal display, an organic light emitting diode, or the like. The trackpad 104-1 may be overlaid on the display 104-2, and when the trackpad 104-1 detects a touch event thereon or nearby, it is communicated to the processor 101 to determine the type of touch event, and the processor 101 may then provide a corresponding visual output on the display 104-2 based on the type of touch event. Although in FIG. 1, the touch pad 104-1 and the display 104-2 are shown as two separate components to implement the input and output functions of the cell phone 100, in some embodiments, the touch pad 104-1 and the display 104-2 may be integrated to implement the input and output functions of the cell phone 100. It is understood that the touch screen 104 is formed by stacking multiple layers of materials, and only the touch pad (layer) and the display screen (layer) are shown in the embodiment of the present application, and other layers are not described in the embodiment of the present application. In addition, in some other embodiments of the present application, the touch pad 104-1 may be covered on the display 104-2, and the size of the touch pad 104-1 is larger than that of the display 104-2, so that the display 104-2 is completely covered under the touch pad 104-1, or the touch pad 104-1 may be disposed on the front surface of the mobile phone 100 in a full-panel manner, that is, a user's touch on the front surface of the mobile phone 100 can be sensed by the mobile phone, so that a full-touch experience on the front surface of the mobile phone can be achieved. In other embodiments, the touch pad 104-1 is disposed on the front surface of the mobile phone 100 in a full-panel manner, and the display 104-2 may also be disposed on the front surface of the mobile phone 100 in a full-panel manner, so that a Bezel-free (Bezel) structure can be implemented on the front surface of the mobile phone.

It is understood that the positioning device 108 may be a receiver of a Global Positioning System (GPS) or a positioning system such as the beidou satellite navigation system, russian GLONASS, etc. After receiving the geographical location transmitted by the positioning system, the positioning device 108 transmits the information to the processor 101 for processing or transmits the information to the memory 103 for storage. In still other embodiments, the positioning device 108 may also be a receiver of an Assisted Global Positioning System (AGPS) that assists the positioning device 108 in performing ranging and positioning services by acting as an assistance server, in which case the assistance positioning server provides positioning assistance by communicating with the positioning device 108 (i.e., GPS receiver) of an electronic device, such as the handset 100, over a wireless communication network. In other embodiments, the location device 108 may also be a Wi-Fi access point based location technology. Since each Wi-Fi access point has a globally unique MAC address, the mobile phone 100 can scan and collect broadcast signals of surrounding Wi-Fi access points when the Wi-Fi is turned on, and thus can acquire the MAC address broadcasted by the Wi-Fi access point; the electronic device sends the data (e.g., MAC address) indicating the Wi-Fi access points to a location server through a wireless communication network, and the location server retrieves the geographical location of each Wi-Fi access point, and calculates the geographical location of the mobile phone 100 according to the strength of the Wi-Fi broadcast signal and sends the geographical location of the mobile phone 100 to the positioning device 108 of the mobile phone 100.

The audio circuitry 109, speaker 113, microphone 114 can provide an audio interface between a user and the handset 100. The audio circuit 109 may transmit the electrical signal converted from the received audio data to the speaker 113, and convert the electrical signal into a sound signal by the speaker 113 to output. On the other hand, the microphone 114 converts the collected sound signal into an electrical signal, converts the electrical signal into audio data after being received by the audio circuit 109, and outputs the audio data to the RF circuit 102 to be transmitted to, for example, another cellular phone, or outputs the audio data to the memory 103 for further processing.

For example, a mouse via a Universal Serial Bus (USB) interface, and a subscriber identity module card (SIM) card provided by a telecommunications carrier via metal contacts on a SIM card slot. Peripheral interface 110 may be used to couple the aforementioned external input/output peripherals to processor 101 and memory 103.

The mobile phone 100 may further include a power supply device 111 (such as a battery and a power management chip) for supplying power to each component, and the battery may be logically connected to the processor 101 through the power management chip, so as to implement functions of managing charging, discharging, and power consumption through the power supply device 111.

Although not shown in fig. 1, the mobile phone 100 may further include a camera (front camera and/or rear camera), a flash, a micro-projector, a Near Field Communication (NFC) device, etc., which will not be described herein.

The snapshot recorded in the embodiment of the application is generated after the terminal captures the screen of the display interface of the application. The snapshot is described in detail below with reference to fig. 2 and 3:

as shown in fig. 2, a WeChat chat interface 201 shown in (a) of fig. 2 is displayed in the display screen of the terminal. After the terminal receives the operation of exiting the application to the background, the terminal captures a screen of the wechat chat interface, and generates a snapshot 202 of the wechat application as shown in (b) in fig. 2.

Referring to fig. 2 and as shown in fig. 3, when the terminal needs to open the wechat application according to the snapshot 202, the terminal first enters a snapshot display interface shown in (a) of fig. 3. When the terminal detects an operation in which the snapshot 202 is selected (for example, an operation in which the user clicks the snapshot 202 shown in (a) in fig. 3), the terminal restores the wechat application to the wechat interface 201 shown in (b) in fig. 3.

Currently, in order to reduce the storage space occupied by the snapshot, a fixed compression ratio is set in the terminal. If the compression ratio is configured in the terminal, the terminal may compress the snapshot according to the compression ratio after generating the snapshot. And the compressed snapshot is stored in the terminal, so that the storage space occupied by the snapshot can be reduced.

However, once the compression ratio is set in the terminal, it cannot be changed. And the terminal compresses the snapshot according to the compression ratio whether the available storage space is sufficient or not. When the compression ratio is a small compression ratio, the compressed snapshot occupies a small storage space, but the pixels of the snapshot also become low. This will likely affect the user's visual experience with the snapshot functionality. Therefore, when the available storage space of the terminal is larger than the preset value, the terminal does not need to reduce the storage space occupied by the snapshot by compressing the snapshot.

The method for processing a snapshot provided in the embodiment of the present application may be applied to the mobile phone 100 shown in fig. 1, and the method for processing a snapshot provided in the embodiment of the present application will be described in detail below with reference to specific embodiments. As shown in fig. 4, the method includes:

step 101, the terminal determines an available storage space of a memory of the terminal.

The available storage space of the memory is also the remaining storage space in the memory.

In the embodiment of the present application, a memory is a Random Access Memory (RAM), and a flash memory is a flash memory (flash for short) for example.

The available storage space of the memory is the storage space in the RAM that is not occupied by the system, application programs, data, or the like of the terminal.

It should be understood that the available memory space in the RAM is constantly changing as the terminal is running. For example, when the number of applications running on the terminal increases, the available storage space in the RAM decreases accordingly; as the applications run by the terminal decrease, the available memory space in the RAM increases accordingly.

Taking the memory as 4G as an example, and the memory used by the terminal is 3G, the available storage space of the memory is 4G-3G — 1G.

And 102, the terminal determines the compression ratio of the snapshot in the processing terminal according to the relation between the available storage space and the preset threshold value. The compression ratio determined by the terminal is the first compression ratio or the second compression ratio.

In this embodiment of the application, the second compression ratio is smaller than the first compression ratio, so that the storage space occupied by the snapshot processed with the second compression ratio is smaller than the storage space occupied by the snapshot processed with the first compression ratio.

Illustratively, the first compression ratio is 1.0 and the second compression ratio is 0.7.

It should be noted that, when the terminal processes the snapshot by using the first compression ratio of 1.0, the terminal may not perform compression processing on the snapshot, but directly store the snapshot in the cache of the memory. And when the terminal processes the snapshot by adopting the second compression ratio, the terminal processes the snapshot according to the compression ratio of 0.7 and stores the compressed snapshot in the cache of the memory.

For example, taking the snapshot pixel as 720 × 1080 as an example, the pixels of the snapshot generated after the terminal processes the snapshot according to the compression ratio of 0.7 are: (720 × 0.7) × (1080 × 0.7) ═ 504 × 756. After the terminal processes the snapshot according to the compression ratio of 0.7, the storage space occupied by the snapshot can be reduced by about 50%, so that the problem of insufficient available storage space of the terminal memory caused by the fact that the snapshot occupies a large amount of memory space is solved.

And 103, processing the snapshot by the terminal according to the compression ratio. And the storage space occupied by the snapshot processed by the first compression ratio is larger than that occupied by the snapshot processed by the second compression ratio.

Specifically, the storage space occupied by the snapshot processed by the second compression ratio in the memory is smaller than the storage space occupied by the snapshot processed by the first compression ratio in the memory.

Based on the above technical solution, the method for processing a snapshot provided by the present application: and the terminal determines the compression ratio of the processed snapshot according to the available storage space of the memory of the terminal. The terminal processes the snapshot according to the determined compression ratio; the storage space occupied by the snapshot processed by the first compression ratio is larger than that occupied by the snapshot processed by the second compression ratio. Therefore, the terminal can flexibly process the snapshot by adopting different compression ratios according to the size of the available storage space of the terminal memory. The scheme can be applied to the field of Artificial Intelligence (AI) of terminals, computer vision and image processing.

With reference to fig. 5, in a possible embodiment, before step 102, the method provided in this embodiment may further include:

and step 104, the terminal determines the memory state of the memory according to the relation between the available storage space and the preset threshold value.

The preset threshold comprises a first preset threshold and a second preset threshold; the memory state of the memory includes a first state and a second state. The first state represents that the available storage space is greater than or equal to a first preset threshold. The second memory state indicates that the available storage space is less than a second predetermined threshold. The first preset threshold and the second preset threshold may be the same or different.

And the memory state set by the terminal in the Nth period is used for representing the relation between the available storage space determined by the terminal in the Nth period and the preset threshold. N is a positive integer.

It should be understood that, in a period after the nth period, the relationship between the available storage space determined by the terminal in the nth period and the preset threshold may be determined according to the memory state set by the terminal in the nth period.

For example, in the N +1 th period, the terminal determines that the memory state set in the nth period of the terminal is the first state, and then the terminal may determine, according to the first state, that the available memory space determined by the terminal in the nth period is greater than or equal to the first preset threshold.

In a possible implementation manner, the terminal may further determine the memory state of the memory according to a proportional relationship between the available storage space and the memory.

For example, when the terminal sets that the available storage space is greater than or equal to 25% of the memory, the terminal determines that the memory state of the terminal memory is a first state, and when the available storage space is less than 25% of the memory, the terminal determines that the memory state of the terminal memory is a second state.

That is, in practical application, for a terminal with a memory of 4G, when the available storage space is greater than or equal to 1G, the terminal determines that the memory state of the terminal is the first state. And when the available storage space is less than 1G, the terminal determines that the memory state of the terminal is a second state.

As a possible implementation, as shown in fig. 6, step 104 may be implemented by:

step 1041, the terminal determines that the available storage space of the memory is greater than or equal to a first preset threshold, the terminal determines that the memory state of the memory is set to be a first state, and records the time for setting the first state.

In a possible implementation manner, if the terminal determines that the memory state of the memory is the second state in the nth period. And the terminal determines that the available memory space of the memory is greater than or equal to a first preset threshold value in the (N + 1) th period, and the terminal updates the memory state of the terminal to be the first state.

And if the terminal determines that the memory state of the memory is the first state in the Nth period. The terminal determines that the available memory space of the memory is greater than or equal to a first preset threshold value in the (N + 1) th period, the terminal keeps the memory state of the terminal to be a first state, and the terminal acquires the time for setting the first state.

It should be noted that, if the terminal is in the nth cycle to the N + m cycle, it is determined that the memory states of the terminal are all the first states. And the terminal determines the time for setting the first state recorded in the Nth period and determines whether the difference between the time for setting the first state and the current time is greater than a first preset time difference. If the difference between the time for setting the first state and the current time is greater than the first preset time difference, the terminal memory available storage space is greater than or equal to a first preset threshold value and lasts for a first preset time period. The terminal determines that a first preset condition is met between the available storage space of the terminal and a first preset threshold. Further, the terminal determines that the compression ratio of the snapshot in the processing terminal is the first compression ratio. m is a positive integer.

As a possible implementation, as shown in fig. 6, step 104 can also be implemented by:

step 1042, the terminal determines that the available storage space of the memory is smaller than a second preset threshold, the terminal determines that the memory state of the memory is set to be a second state, and records the time for setting the second state.

In a possible implementation manner, if the terminal determines that the memory state of the memory is the first state in the nth period. And the terminal determines that the available memory space of the memory is smaller than a second preset threshold value in the (N + 1) th period, and the terminal updates the memory state of the terminal to be a second state.

And if the terminal determines that the memory state of the memory is the second state in the Nth period. The terminal determines that the available memory space of the memory is smaller than a second preset threshold value in the (N + 1) th period, the terminal keeps the memory state of the terminal in the second state, and the terminal acquires the time for setting the second state.

It should be noted that, if the terminal is in the nth cycle to the N + m cycle, it is determined that the memory states of the terminal are all the second states. And the terminal determines the time for setting the second state recorded in the Nth period and determines whether the difference between the time for setting the second state and the current time is greater than a second preset time difference. And if the difference value between the time for setting the second state and the current time is greater than a second preset time difference value, the available storage space of the terminal memory is smaller than a second preset threshold value and lasts for a second preset time period. And the terminal determines that the available storage space of the terminal and a second preset threshold value meet a second preset condition. Further, the terminal determines that the compression ratio of the snapshot in the processing terminal is the second compression ratio.

Therefore, the terminal can determine whether the memory state of the terminal changes in the continuous period by setting the memory state. Furthermore, the terminal determines the duration of the current memory state of the terminal according to the difference between the setting time of the current memory state of the terminal and the current time, so that the terminal can accurately determine the relationship between the available storage space and the preset threshold value.

Since the compression ratios determined by the terminals are different, the modes of the terminal processing the snapshot are different, and therefore the following description is provided respectively:

example 1) compression ratio of the first compression ratio

As a possible embodiment of the present application, as shown in fig. 6, step 102 in the embodiment of the present application may be implemented in the following manner:

step 1021, when the first preset condition is met, the terminal determines that the compression ratio is the first compression ratio.

Wherein the first preset condition is as follows: the available storage space is greater than or equal to a first preset threshold; alternatively, the available storage space is greater than or equal to a first preset threshold value and lasts for a first preset time period.

Illustratively, the first preset threshold is 1100M and the first preset time period is 20 minutes.

As a possible implementation manner, as shown in fig. 6, when the first preset condition is: when the available storage space is greater than or equal to the first preset threshold and lasts for the first preset time period, before step 1021, the method may further include:

in step 1022, the terminal determines whether a difference between the time for marking the first state and the current time is greater than a first preset time difference.

In a possible implementation manner, a memory monitoring program is provided in the terminal, and the terminal periodically determines a relationship between an available storage space of the terminal and the memory through the memory monitoring program.

For example, in step 1022, the relationship between the available storage space of the terminal and the first preset threshold determined by the terminal memory monitoring program is shown in fig. 7. Wherein, the first preset threshold is 1100M.

The terminal continuously records the available storage space, and when the available storage space is greater than or equal to 1100M within the continuous preset time, the terminal determines that the relation between the available storage space of the terminal and the first preset threshold meets a first preset condition.

In case that the terminal determines that the difference between the time of marking the first state and the current time is greater than the first preset time difference, the terminal performs step 1023.

Step 1023, the terminal determines that the available storage space of the memory and the first preset threshold value meet a first preset condition.

It should be noted that, the terminal determines that the difference between the time for marking the first state and the current time is greater than the first preset time difference, and the duration of the time period during which the available storage space of the terminal is greater than or equal to the first preset threshold is greater than the duration of the first preset time period. Further, the terminal determines that a relationship between the available storage space of the terminal and a first preset threshold satisfies a first preset condition.

It should be understood that the memory state of the available storage space is the first state, and the difference between the time of marking the first state and the current time is greater than the first preset time difference, the terminal determines that the available storage space is greater than or equal to the first preset threshold, and lasts for the first preset time period. Furthermore, the terminal determines that the available storage space of the memory and the first preset threshold value meet a first preset condition.

In case that the terminal determines that the difference between the time marking the first state and the current time is less than or equal to a first preset time difference, the terminal performs step 101.

It should be noted that, the difference between the time for marking the first state and the current time is determined by the terminal to be less than or equal to the first preset time difference, which indicates that the duration of the time period during which the available storage space of the terminal is greater than or equal to the first preset threshold is less than the duration of the first preset time period. Further, the terminal determines that the relation between the available storage space of the terminal and the preset threshold does not satisfy a first preset condition.

Accordingly, with reference to fig. 6, step 103 in the embodiment of the present application may be implemented by:

and step 1031, the terminal processes the first snapshot according to the first compression ratio. And the terminal stores the first snapshot processed by adopting the first compression ratio in a memory of the terminal.

The first snapshot is a snapshot between the current time and a first time node; the first time node is a time node after the current time and when the compression ratio determined by the terminal changes.

For example, the terminal generates a first snapshot before the current time reaches a first time node: snapshot 1, snapshot 2, and snapshot 3. And the terminal respectively processes the snapshot 1, the snapshot 2 and the snapshot 3 by adopting a first compression ratio. And storing the compressed snapshots 1, 2 and 3 in the memory of the terminal. And further, the terminal stores the compressed snapshots 1, 2 and 3 in a cache of a terminal memory, so that the terminal can call the snapshots more quickly.

For the cached snapshot, the terminal processes the snapshot by using the method described in step 1032 or step 1033.

Step 1032, the terminal processes the cache snapshot stored in the flash memory by adopting the first compression ratio, and replaces the cache snapshot processed by adopting the second compression ratio in the memory by adopting the cache snapshot processed by the first compression ratio.

And the cache snapshot stored in the flash memory is not processed by adopting the first compression ratio.

For example, at the current time, the terminal determines that a cache snapshot is stored in a flash memory of the terminal: snapshot 4 and snapshot 5. Snapshot 4 and snapshot 5 are the original-scale snapshots generated by the terminal. Correspondingly, the snapshot 4 compressed by the second compression ratio and the snapshot 5 compressed by the second compression ratio are stored in the memory of the terminal.

The terminal processes the snapshot 4 and the snapshot 5 with a first compression ratio. The terminal replaces the snapshot 4 processed by the second compression ratio in the memory with the snapshot 4 processed by the first compression ratio; and replacing the snapshot 5 processed by the second compression ratio in the memory by the snapshot 5 processed by the first compression ratio.

1033. And the terminal replaces the cache snapshot processed by the second compression ratio in the memory by the cache snapshot processed by the first compression ratio. Wherein the cache snapshot stored in the flash memory is a cache snapshot processed by adopting a first compression ratio,

for example, at the current time, the terminal determines that a cache snapshot is stored in a flash memory of the terminal: snapshot 6 processed with the first compression ratio and snapshot 7 processed with the first compression ratio. Correspondingly, a snapshot 6 compressed by the second compression ratio and a snapshot 7 compressed by the second compression ratio are stored in the memory of the terminal.

The terminal replaces the snapshot 6 processed by the second compression ratio in the memory with the snapshot 6 processed by the first compression ratio; and replacing the snapshot 7 processed by the second compression ratio in the memory by the snapshot 7 processed by the first compression ratio.

It should be noted that, when the terminal does not process the cache snapshot stored in the flash memory according to the first compression ratio, the terminal processes the cache snapshot in the terminal according to the scheme described in step 1032.

When the terminal uses the first compression ratio to process the cache snapshot stored in the flash memory, the terminal uses the scheme recorded in step 1033 to process the cache snapshot in the terminal.

In a possible implementation manner, after the terminal replaces the cache snapshot processed at the second compression ratio in the memory with the cache snapshot processed at the first compression ratio, the terminal may delete the cache snapshot processed at the first compression ratio stored in the flash memory, so as to achieve the purpose of reducing the available storage space of the terminal flash memory occupied by the snapshots.

Example 2) compression ratio of the second compression ratio

and step 1024, when a second preset condition is met, the terminal determines that the compression ratio is a second compression ratio.

The second preset condition is as follows: the available storage space is smaller than a second preset threshold; or the available storage space is smaller than a second preset threshold value and lasts for a second preset time period.

Illustratively, the second preset threshold is 900M and the second preset time period is 30 minutes.

It should be noted that, in the embodiment of the present application, the first preset threshold and the second preset threshold may be equal or unequal. The first preset time difference and the second preset time difference may be equal or unequal. The terminal can be flexibly set according to actual conditions.

In practical application, the terminal can achieve the purpose of avoiding the terminal from frequently switching and processing the compression ratio of the snapshot by setting the first preset threshold to be larger than the second preset threshold. The terminal can enable the terminal to process snapshots more by adopting the first compression ratio by setting the first preset time difference value to be smaller than the second preset time difference value, so that the terminal is prevented from displaying the snapshots with low pixels for a long time.

As a possible implementation manner, with reference to fig. 6, when the second preset condition is: the available storage space is less than a second preset threshold and lasts for a second preset time period. Before step 1024, the method may further include:

in step 1025, the terminal determines whether the difference between the time for marking the second state and the current time is greater than a second preset time difference.

For example, in step 1025, the relationship between the available storage space of the terminal and the second predetermined threshold determined by the terminal memory monitor is shown in fig. 8. Wherein the second preset threshold is equal to 900M.

And the terminal continuously records the available storage space, and when the available storage space is less than 1100M within the continuous preset time, the terminal determines that the relation between the available storage space of the terminal and the second preset threshold meets a second preset condition.

In case that the terminal determines that the difference between the time for marking the second state and the current time is greater than a second preset time difference, the terminal performs step 1026.

In step 1026, the terminal determines that a second preset condition is satisfied between the available storage space of the memory and a second preset threshold.

It should be noted that, the terminal determines that the difference between the time for marking the second state and the current time is greater than a second preset time difference, and the duration of the time period during which the available storage space of the terminal is smaller than the second preset threshold is greater than the duration of the second preset time period. Further, the terminal determines that a relationship between the available storage space of the terminal and a second preset threshold satisfies a second preset condition.

It should be understood that the memory state of the available storage space is the second state, and the difference between the time of marking the second state and the current time is greater than the second preset time difference, and the terminal determines that the available storage space is smaller than the second preset threshold and lasts for the second preset time period. And then, the terminal determines that the available storage space of the memory and a second preset threshold value meet a second preset condition.

In case that the terminal determines that the difference between the time marking the second state and the current time is less than or equal to a second preset time difference, the terminal performs step 101.

It should be noted that, the terminal determines that the difference between the time for marking the second state and the current time is less than or equal to a second preset time period, which indicates that the duration of the time period during which the available storage space of the terminal is less than the second preset threshold is less than the duration of the second preset time period. Further, the terminal determines that the relation between the available storage space of the terminal and the preset threshold does not satisfy a second preset condition.

step 1034, the terminal stores at least one of the cache snapshot and the first snapshot in the flash memory.

In a possible implementation manner, if a memory of the terminal stores a cache snapshot, the terminal obtains the cache snapshot stored in the memory and stores the cache snapshot in the flash memory. And if the terminal generates a first snapshot between the current time and the first time node, the terminal stores the first snapshot into the flash memory.

For example, the terminal determines that the memory of the terminal includes the cache snapshot at the current time: snapshot 8 and snapshot 9. And the terminal stores the snapshot 8 and the snapshot 9 in the flash memory for backup. The terminal generates a first snapshot between the current time and a first time node: snapshot 10 and snapshot 11, the terminal stores snapshot 10 and snapshot 11 in the flash memory for backup.

In another possible implementation manner, the cache snapshot stored in the memory of the terminal is a snapshot compressed by using the first compression ratio. And the terminal acquires the snapshot compressed by the first compression ratio and stores the snapshot in the flash memory.

Step 1035, the terminal processes at least one of the cache snapshot and the first snapshot according to the second compression ratio, and stores at least one of the cache snapshot and the first snapshot processed by the second compression ratio in the memory.

In a possible implementation manner, if the terminal stores the cache snapshot, the terminal compresses the cache snapshot according to the second compression ratio, and stores the compressed cache snapshot in the memory of the terminal. And if the terminal generates the first snapshot between the current time and the first time node, the terminal compresses the first snapshot according to the second compression ratio and stores the compressed first snapshot in the memory of the terminal.

For example, corresponding to step 1034, the terminal determines that the memory of the terminal includes the cache snapshot at the current time: snapshot 8 and snapshot 9. The terminal processes the snapshot 8 with the second compression ratio and processes the snapshot 9 with the second compression ratio. The terminal adopts a second compression ratio to process the snapshot 8 to replace the snapshot 8 in the cache; and replacing the snapshot 9 in the cache by the snapshot 9 processed by the second compression ratio.

The terminal generates a first snapshot between the current time and a first time node: snapshot 10 and snapshot 11, snapshot 10 being processed with a second compression ratio, and snapshot 11 being processed with the second compression ratio, respectively. And the terminal stores the snapshot 10 processed by the second compression ratio and the snapshot 11 processed by the second compression ratio in the memory of the terminal.

Based on the technical scheme, under the condition that the available storage space of the terminal is sufficient, the terminal determines that the snapshot is processed by adopting the first compression ratio, so that the pixels of the snapshot processed by the terminal are higher, and the visual experience of a user is improved. Under the condition that the available storage space of the terminal is insufficient, the terminal determines to adopt the second compression ratio to process the snapshot, so that the storage space occupied by the processed snapshot can be reduced, and the problem that the mobile phone cannot run smoothly due to the fact that the storage space of the RAM occupied by the snapshot is large is avoided.
